Interesting new data about caldera's ice cap last autumn survey:

...Latest measurements (26 November 2012) Results of the 3 latest surveys and the survey on December 17 1999 are shown on the profiles below. Ablation in summer lowers the surface elevation of the glacier by 4-8 m from spring to autumn. Accumulation of snow restores the elevation during the winter. From autumn 1999 to autumn 2001 cauldron 7 gradually got shallower but apart from that changes were not significant. Between autumn 2001 and 2004 some cauldrons grewn, due to increasing geothermal activity. This increase was accompanied by increased seismicity and uplift (www.vedur.is), the cause probably being magma accumulation under the Katla caldera. After 2004 geothermal activity declined until a sudden increase caused the flood in M&#250;lakv&#237;sl 9 July 2011. Mainly cauldron 16 and 9 grew in size but changes could also be seen in cauldrons 8 and 10...
